Looking for insight into current Guardian PvP builds

I recently got back into the game around a month ago and have been catching up on PvP. I used to play Core GS/Sw+F radiance power Guardian, and it remains my favorite, but from what I have read the build has only gotten worse over the course of the year. I have been trying it with different amulets with varying levels of success but I would like to try something a little more competitive. I've seen a handful of different core and FB builds, and from what I can tell, core is more of a burning-based dps/duelist build, whereas firebrand is still focused on support? I see people running longbow DH every couple matches and it looks like the Test of Faith LB/Sw+Sh, and seems to be decent. I usually play unranked though and when I do play ranked, I'm only in G2/G3 so m perception may not be that great. I was hoping someone with a little more knowledge about the current builds available could help me parse through the options.

While this is primarily aimed at sPvP, I play WvW here and there as well, though I much prefer the smaller-scale fights of roaming to zerging.

the symbol core guardian is the better performing guardian build afaikDH with traps and burning is decentfirebrand isn’t bad but i’m not seeing much of them
